Lisa Ann Walter is schooling Megan Fox.
The “Abbott Elementary” star slammed her fellow actress for tagging SAG-AFTRA in an Instagram post showing off her “Kill Bill” Halloween costume after the labor union issued guidelines banning actors from dressing up as characters from struck TV shows and movies and posting the photos.
“What a rebel,” Walter, who has been active on the picket lines during the actors’ strike, sarcastically tweeted Sunday.
“Keep posturing for stupid s–t, pretty lady. Meanwhile we’ll be working 10 hours a day – unpaid – to get basic contract earners a fair deal.”
In a carousel of photos, Fox posed with fiancé Machine Gun Kelly as Gogo Yubari and Beatrix Kiddo, respectively, from the 2003 Quentin Tarantino flick at the annual Casamigos Halloween bash.
Other celebs attended the party dressed as movie characters, too; “Modern Family” star Sarah Hyland and her husband, Wells Adams, went as Virginia Venit and Happy Gilmore.
Prior to Halloween weekend, SAG-AFTRA released guidelines regarding how actors can dress up for the holiday without breaking strike rules.
The Oct. 18 notice on the union’s official website stressed that actors could “dress up as characters from non-struck content, like an animated TV show,” but should not “post photos of costumes inspired by struck content to social media” — as Fox, 37, did.
Walter, 60, noted in her tweet that SAG-AFTRA doesn’t care “about kids’ costumes. Just Just high pros at fancy parties. Like Megan.”
The “Transformers” star’s Instagram account was flooded with negative comments regarding her costume.
“Why is she being defiant to a group that’s literally fighting for her to make a fair wage,” read one comment, while another rhetorically asked, “Didn’t SAG-AFTRA ask its members to NOT dress as movie characters?”
“Yes girl give it to your union trying to get better wages and benefits for lesser known people than u!” read a third.
Other well-known actors, however, have criticized the costume guidelines.
“Is this a joke?” Mandy Moore wrote on social media earlier this month. “Come on @sagaftra. This is what’s important?”
She continued, “We’re asking you to negotiate in good faith on our behalf. So many folks across every aspect of this industry have been sacrificing mightily for months.
“Get back to the table and get a fair deal so everyone can get back to work. Please and thank you.”
“Little House on the Prairie” alum Melissa Gilbert also blasted the union, calling its guidelines “infantile.”
SAG-AFTRA has been on strike since July 14 over an ongoing labor dispute with the Alliance of Motion Picture and Television Producers (AMPTP). It is their first strike in over 40 years.
